How do I know what tube size to purchase?

Below are three options to find the pump tube you need:

The tube size, represented by a number or letter, is molded on to one of the tube fittings.

Locate the model on the data label located on the side of the pump and reference it in the output chart in the manual. The output chart indicates the tube that was shipped in the pump. The output chart is in the catalog or if you know the pump series, you can refer to the output chart in the series manual in Downloads.

How often should I change the duckbill (where applicable) and the pump tube?

The pump tube and duckbill are wear parts and replacement is part of routine maintenance. Pressure, run time and the liquid injected are just some of the factors that can affect tube life. Replacing the tube and duckbill before they are worn out is preventative maintenance practice and is recommended by Stenner. The first time the pump tube is replaced is an indication of the approximate life of the tube in that particular application. It is very important to verify that the worn tube was due to normal wear and not an outside contributing factor that could have shortened the tube’s life. Pump tubes and rubber components are considered perishable consumables and are not covered under warranty. For assistance, Contact Us. Go to top

Pumps – Econ Integrator™ (E20R)

Can the Econ Integrator™ use an existing water meter that is wired to a house controller for livestock operations?

Yes, an internal signal repeater enables the water meter to send the dry contact signal to a controller. Go to top

Pumps – Econ Integrator™ (E20R)

Will the standby mode interrupt the pulse signal to the controller?

The standby mode disables the pump. Because of the internal signal repeater, the standby mode does not interrupt the pulse signal to the controller when there is power applied to the pump. Go to top

Pumps – Econ Integrator™ (E20R)

What type of water meter can be installed?

The Stennicator needs a dry contacting (pulse) water meter and electricity to operate. Go to top

Pumps – Econ Integrator™ (E20R)

What type of signal comes from the repeater relay?

The repeater relay provides a dry contact output signal that replicates the dry contact input signal that the pump receives. Go to top

Pumps – Econ Integrator™ (E20R)

Will the repeater relay transmit a signal when the pump is operating?

Yes, the repeater will pass through every signal that comes from the water meter. The signal from the water meter will transmit whether the pump is operating or not operating. Go to top

The Stennicator works with a dry contacting (pulse) water meter. Go to top

Pumps – Econ Stennicator

Can the output be adjusted?

The pump output is not adjustable, it injects at a fixed ratio of 1:128 (1 ounce per 1 gallon). Go to top

Pumps – Econ Stennicator

What are the available settings on the pump?

The settings on the Stennicator pulse dial are labeled I PPG, 10 PPG, 1 PPL, STBY and PRIME. The pump accepts a signal from a water meter providing a dry contact rate of 1 or 10 pulses per gallon, or 1 pulse per liter and proportionally injects directly into the water line at a rate of 1:128 to treat process flow rates up to 2.7 gallons per minute (162 gallons per hour). Go to top

Pumps – Econ Stennicator

How long is the prime cycle?

After setting the dial to PRIME, there is a 5 second delay before the pump starts to run. After the delay, the prime setting initiates a 60 second run cycle at maximum speed to prime the pump. At the end of the prime cycle, the pump will stop and will remain stopped until it is set to a contacting rate. Go to top

Pumps – Econ Stennicator

Does the signal from the water meter work in standby? Does the signal from the water meter work when the pumps is dosing?

When the pump is placed in the standby setting (STBY), it will not dose when it receives a signal from the water meter. The signal from the water meter will continue to repeat if the is pump is dosing or not dosing. Go to top

Pumps – Econ Stennicator

How can I get more flow?

The volume can be doubled by using 2 Stennicator pumps to keep pace at higher flow rates. By properly wiring the signal cables each pump will deliver at a ratio of 1:256 (0.5 oz. per gallon) to achieve a ratio of 1:128 (1 oz. per gallon). This will allow a ratio of 1:128 up to flows of 5.4 gallons per minute.

A constant alarm indicates a locked rotor motor failure. Unplug the pump to reset the alarm. If the roller assembly isn’t turning, the motor may need to be replaced. An intermittent alarm indicates that the flow rate is exceeding the amount that the M128 model can operate within to provide the 1:128 ratio. Go to top

Proportional Injection System

Can I reconfigure, or order, the Proportional Injection System with a 1” or larger water meter?

No, however, the lid design helps to prevent a vacuum from developing within the tank. The cap design allows air to enter the tank as the solution is depleted, so a vacuum does not form. It is important that the cap is not over-tightened. Go to top

Water Meters

Do I need my water meter to match my pipe size?

Water meters should be sized by the system flow rate, not by the pipe size alone, and comply with all city or state regulations. Refer to the manufacturer’s water meter manual for sizing guidelines. Go to top

Pump Control Module (PCM)

Can the PCM run multiple pumps?

No, the PCM has a single receptacle and is not designed to run multiple pumps. Its current rating is 1.8 amps. A 120V/60Hz Stenner Classic series pump has a load of 1.7 amps or 204 watts. Go to top

Pump Control Module (PCM)

When wiring the PCM to a dry contact water meter, is polarity important?

No, polarity is not an issue as long as the wires are connected securely; the water meter signal is not polarity sensitive. Go to top

The PCM operating time range is factory set according to the specific model selected, but it can be converted to any of the other available time ranges, so it is not necessary to purchase another model. The time range is converted by changing the position of the jumpers on the printed circuit board located under the PCM’s cover. The PCM Manual contains the instructions. Go to top
